PROOF-PRESS.

SPECIFICATION forming part of Letters Patent No. 238,525, dated March 8, 1881.

Application filed January 11, 1881.

I this specification, and to the letters of reference marked thereon, in which Figure l is a front elevation of my improved proof-press. Fig. 2 is an end sectional view of the same. Fig. 3 is a View of one of the circular plates of metal F. Fig. 4; is a view of one of the boxes E and its regulating-screw I.

In the drawings like parts of the invention are designated by the same letters of reference. The nature of the present invention consists in certain improvements in the construction of proof-presses for use by printers, as more fully hereinafter set forth, the object of the invention being the production of aproof-press applicable to the taking of proofs from types secured in 2 5 a chase or locked up upon a galley, which press shall be easily operated, and can be afforded at a low cost to the consumer.

To enable those skilled in the art to make and use my invention, I will describe its con- 0 struction and operation.

3 5 ted, as at c, to receive the boxes E, provided with central openings, within which are inserted the circular plates of metal F, upon the inner side of each of which is secured eccentrically a pin, f, and upon the outer side or face a crank-arm, g, by which the circular plate of metal F may be turned as desired, changing the position of the eccentric-pin f.

G shows a roller formed of vulcanized rubber or like material and supported upon a 4 5 shaft, H. This shaft is provided at each end with a central opening, within which the eccentric-pins f have a bearing, so that as the position of these eccentrics is changed the shaft H and roller G may be raised or lowered, as

so desired.

(No model.)

I are thumb-screws, passed through the upper portions of the side 0, and engaging with screw-threaded openings in the boxes E, by which the position of the boxes E is regulated; and J are set-screws placed above and below the boxes E, upon which they have a bearing to retain the boxes in any desired position in which they may be placed.

Such being the construction, the operation is as follows: The press is intended to enable the printer to take proofs from a form of types placed upon a galley or secured in a chase. As

the type secured upon a galley will stand higher than if secured in a chase, means are provided for raising the roller G, secured upon the shaft H, consisting of the circular plates of metal F, provided with the eccentric-pins f, having their bearings in a shaft, H. When a proof is to be taken from a form secured in a chase the crank-arms g, attached upon the faces of the circular plates of metal F, are turned up, so that the eccentric-pinsf, upon the opposite sides of the circular plates of metal F, are lowered, lowering the roller G held upon the shaft H, and when a proof is to be taken from a galley the crank-arms g are turned down, by which the eccentric-pins f are raised, raising the roller. G secured upon the shaft H. When desired the position of theboxes E is varied by manipulating the thumb-screws I, and when adjusted to any particular position are held in that position by the set-screws J, placed above and below them. The roller G upon the shaft H having been raised or lowered, as the character of the proof to be taken requires, the form is inked, a sheet of paper laid upon the same, and the press passed over the paper, the roller Gr bearing upon the same sufficiently to cause an impression to be taken from the type upon the paper. In this operation the rollers D facilitate the movement of the press.

A proof-press thus constructed can be afforded at a low price to the consumer, and, as it can be used to take a proof from a form secured either in a chase or upon a galley, will be found exceedingly useful to the printer.

Having now set forth my invention, what I claim as new is In a printers proof-press, the combination of she following elements: a frame, A, proshaft, H, constructed and operating substanvided with a handle, 13, and sides U, having tially as and for the purpose specified.

the rollers D, the boxes E, within which are received the circular plates of metal F, having WILLIAM QUAIL upon one side the eccentric-pins], and upon In presence of the opposite side the crank-arms g, the thumb- WILLIAM V.
